"In May 2007 Josh and I were among those who went to Galapagos with a large group from the Center for Inquiry. As we walked with the guided parties over the islands, Josh took every opportunity to film the wildlife. Occasionally he would turn the camera on me, and I would ad lib a few words about whatever animals we were looking at. These 'vignettes' were unscripted and unrehearsed, and there was no time for any "Take 2" repetitions, because the guided walk was moving on."
Richard

The only logic ... ( 8 months ago by prototypo)

The only logic explanation for the existence of life on Earth: scientific creation made by very advanced extraterrestrials who created human beings "in their image". They are the the gods and angels from our legends. Evolution and God are two outdated stupid dogmas.

@prototypo ... ( 5 months ago by justdidthistocommen1)

@prototypo Evolution is not outdated in the scientific community (you know, the people that work to understand the universe), and as for your statement that your belief is the only logical one, consider what hard, non refutable evidence you have for it. Cite this evidence if you intend to debate me if not don't bother replying as i'll have plenty of evidence supporting evolution to throw at you. And if your reply is to deny the evidence...well then thats just purposeful ignorance.

Richard Dawkins has ... ( 5 months ago by 8yankee)

Richard Dawkins has gone off the rails:
search for Richard Dawkins and male privilege on Phil Plait's Bad Astronomy blog.
Participating in flaming a woman because she dares to say 'don't objectify me at a conference'? Poorly done, Dawkins.

@8yankee So ... ( 4 months ago by DanielJGC)

@8yankee So basically a man asked a woman if she wanted coffee? OH NO SOMEBODY CALL THE POLICE! All she has to do is politely refuse. He has every right to ask her that. If she feels "threated" by that question then that's something she has to deal with.

Dead-to-the-spirit ... ( 4 months ago by SpencerBenedict2nd)

Dead-to-the-spirit deluded "God Delusion" author & blithering fool scientist goon Richard Dawkins another "leader" given to the profane masses is another useful idiot for Jesuit machinations-C.O.
Jesuitical: pertaining to the Jesuits or their principals; designing; cunning; deceitful; prevaricating
The Jesuit Order completely altered the education system to suit their Evo-Hoax agenda to discredit the Bible. They cant have a Satanic society of 'Do as Thou Wilt' if people still follow the Bible

@iwalrus11 you ... ( 3 months ago by AmateurVisions)

@iwalrus11 you right in saying WHY he said that...but in many, many, many university biology courses....there is an invisible line between 'evolve to suit the environment' and 'adapting to a suitable niche'
The basis that explains both in conjunction: mutations in a gene are what cause changes in an animal (evolution), and whatever the change, as a result of chance....will allow those animals to thrive in a particular environment (niche) that suits them (adaptation).
I hope I've explained it?

@slicingwater haha, ... ( 3 months ago by AmateurVisions)

@slicingwater haha, "too bad I won't be there to see". Absolutely brilliant line, my friend! Evolution happens on the scales of millions of years. I would seriously find a way to freeze myself in time.....just to see the beautiful works of evolution happen. That would be a dream come true. If only.
